Public bug reported:
I had Ubuntu 18.04 installed, running XFCE (Xubuntu session), and audio
worked fine, using either the built-in speakers/mic on the laptop or via
a USB headset when that was plugged in.
However, after upgrading to 20.04, the built-in audio device is no
longer available until I run "sudo alsa force-reload". Wthhout that WAR,
all I see is a dummy audio device. Luckily the USB headset works fine,
if plugged in.
